Aamilah learned in science class that water freezes at 0°C, which made her curious about the freezing points of other clear liquids. She decided to investigate by testing saltwater, vegetable oil, and clear soda. She poured 50 mL of each liquid into three identical plastic containers. Then she placed all three containers in the freezer at the same time and put the same type of thermometer in each one. Every ten minutes, Kendra checked the temperatures and wrote down what she observed in her science journal. What is the independent variable?
Type of liquid
When one substance is uniformly dissolved in a liquid, it is called a ______________. (Examples: sweet tea, salt water, cake)
Solution
This type of storm occurs over warm, tropical water. Its winds are equal or greater than 74 mph and it has a spiral-shaped cloud formation.
Hurricane
What is the term for when light travels through something?
Transmit (Or Transmission)
When objects collide, the energy from one object _________ to the other object.
While baking bread, Emma wondered whether different brands of yeast would affect how much the bread rises. She decided to test this by baking three loaves using three different yeast brands. For each loaf, she used the same amounts of flour, water, sugar, and yeast. All the bread was baked at the same oven temperature. As soon as each loaf came out of the oven, Stephanie used the same ruler to measure how tall the bread was. What is the dependent variable?
Height of the bread
